Bug#570466: not fixed after all

[Rémi Letot <hobbes@poukram.net>]

Hello,

the stability of my laptop was apparently due to a missing firmware file
(R600_rlc.bin), which prevented DRI2 to work. Now that I have that file
back (I also upgraded to latest 2.6.33 kernel from experimental), I have
problems again with KMS/DRI2.

However the problem evolved, as my laptop does not completely crash
anymore. Only the screen randomly turns blank and doesn't come back.

For example, I can still switch to a VT. The screen somehow flickers but
remains blank, but I can blindly login and issue commands or reboot. I
suspect that my X session is still useable, but of course without
knowing where my pointer is, it's quite complicated to prove :-)

I logged in through ssh, and X is no longer using 100% CPU. I have no
error in syslog or the Xorg log, so it seems that the beast is blind but
didn't notice anything unusual.

Tell me if I can help further.

Thanks,
